so what's up with 850-900 cals burned in less than an hour

I've been wondering the same thing. The most I've been able to burn in an hour doing anything is about 350. I have 40-50 lbs to lose and am putting everything I have into my workouts. I guess though, it's really not necessary to burn that many calories because then you have to eat to make up those calories. idk either....
youll do wonders just working out 3 days a week for under an hour and resting.
Perfect bodies are built in the kitchen and while you sleep!
Everything else is secondary!
This is a good article that can be applied to just about anything!

I weigh 227lbs, but can go very hard on the elliptical for over an hour. I keep my heartrate around the 85% mark during that time. I take the calories burned from the machine, which range from 800 - 900. I know this can be off, so I don't eat all of my exercise calories.
I think a lot of people forget there is a distance component to calorie burn. It isn't just heartrate. Otherwise, I'd just sit on a coutch and watch exciting movies. It takes energy to move a certain weight a certain distance. Our bodies get more efficent with exercise, so that is where heartrate comes in.0 -
I can do 40 minutes of Body Combat and burn 500-600 calories. I'm 50 pounds overweight and I have heard that the more you have to lose the more you burn at first. My friend who is 130 pounds does the same thing and only burns about 300 calories.0

Your calorie burn depends on two things:
Intensity of the effort (i.e. amount of oxygen consumed per minute)
Body weight
That's it.
Heavier people doing the exact same exercise at the exact same intensity will burn more calories than lighter people, and vice versa.
I use running at 6 mph as a good example, because it makes the arithmetic more simple. Running at this speed has an intensity of about 10 METs (MET stands for metabolic equivalent and is equal to the amount of oxygen the avg person consumes at rest, or 3.5 mlO2/kg/min).
A 132lb (60kg) person running 6 mph will burn 600 calories per hour
A 154lb (70kg) person running 6 mph will burn 700 calories per hour
A 176lb (80kg) person running 6 mph will burn 800 calories per hour
A 198lb (90kg) person running 6 mph will burn 900 calories per hour
A 220lb (100kg) person running 6 mph will burn 1000 calories per hour
So that's what it takes to burn 1000 calories in an hour. If you are a lighter person or you can't run 6 mph for an hour, then you are most likely not burning 1000 cals in an hour, regardless of where you are getting that number.
Many people get overestimated readings from HRMs because they either have cheapo models, or they don't have the devices set up properly.
The biggest mistake is an incorrect HR max. HRMs default to an age-predicted value (usually 220-age) if your actual max HR is higher than that (not uncommon, esp for women) than the HRM assumes you are working at a much higher intensity than you actually are.
Other conditions that will inflate HRM calorie numbers:
Strength training
Upper-body work
Thermal stress0 -
Maybe I should clarify for some.. I (ME) do NOT burn 850 cals an hour. I do use an HRM and it generally has me burning between 350-400 in an hour workout, sometimes less if I do more weights (duh, not as much of an elevted heartrate there).
But on my news feed people who (as far as I know) are about my weight and same sex - burn close to 1000 cals in a single workout. And it's often not even running, but rather a "walk off the pounds" type of exercise. That being said they say they use an HRM as well.
I am just confused. I know I should be happy with what I'm burning. Sometimes wish I had more to lose, it may come off easier :P - at least at first.
Most of the time, those higher numbers are bogus. HRMs are not magic devices. If they are cheap, or not set up properly, they can be wildly inaccurate.0 -

Thermal stress
Question for you Azdak, are you familiar with how much thermal stress may skew the results? Is it a minor discrepancy or can it be a major one?0 -
I agree and the MFP numbers are usually way over the top. I typically take 25-50% off what it recommends if I am not tracking with HRM myself.
Also, soooo many people keep saying they are using the elliptical machines. I find this the most useless workout for HR and therefore cal burn. Not much better than a recline bike! I don't know how you can burn 800 on the thing, I have only even burnt about 200-300 cals on one.
Go for a run or a spin class people - probably the only two things that will burn 600-800. Zumba too I do every now and then and that is definitely 800 cals if you put everything into it.
I'll show you how to burn more calories on an elliptical.0 -
Its when people post theyve burnt 2000 cals doing food prep. WTF????0

i do not use MFP recomended cals for time as i think they are way out! i use HRM and it works well for me.0

I think what’s throwing you off is you look at peoples profiles and they are a healthy weight, they aren’t double your weight so you don't understand why they are burning so much. The truth is all the photos on their profile are old, they are 20-40+ lbs heavier, admit it people! Mine are 2+ years old and 10-12lbs lighter but that's b/c I started on MFP 2+ years ago right before gaining 8lbs on my honeymoon. That's my excuse and I'm sticking to it, LOL!
I can't imagine burning 800 cals in an hour of Zumba, I've done it 2x, it was fast paced dancing but by no means as intense or nearly as fast paced compared to Turbo Fire or even spinning.
Just take it with a grain of salt and focus on you. All the "good work!" comments on your news feed mean nothing, do it for you.
All my photos are less than a year old and show me at my heaviest. Also I am 3x your size and I can easily burn 900-1000 calories in an hour. I wear a heart rate monitor and I have caught myself at 92% my max heart rate, so I slow down, take a rest and then jump back into it. I think for anyone your size to burn 500 cals in a hour should be plenty.0 -
Like the other said, it totally depends on YOU! Lots of factors go into it.
Im over 200lbs, and can easily burn 800 calories doing an hour of cycle/spin class. But if I am on the elliptical, I usually burn 300-350 in 30 minutes. Not quite as much but I probably dont push as hard either~
Everyone is different, best thing to do is to work on you and not worry about anyone else!

I burn 800-1000 calories per workout session and it's very intense...I also wear a HRM....0

A lot of people here seem to burn ^^ that many calories in one session of exercise, sometimes the title does not even seem to be vigorous exercise. How is this possible?
At my total max I burn 600cals in an hour of cycling class. I realize that if people weigh more they'll burn more, but I don't know if everyone that does this weighs more.
An hour at the gym with running, elliptical, stairclimber and so on brings me 300-400 cals MAX. I can't push myself any harder or I'd pass out.
What gives? what am I doing wrong?
It's because maybe you have that elliptical set on ONE instead of 20, you're a smaller girl... I can burn 800-900 calories in an hour on the elliptical or running, but I am a 240 lb. male. That is why.0 -
In a solid hour I can burn over 2000 based on bodyweight......dont worry about it, youve got it down pat.0

I've burned more than 800 calories in a hour by running for an hour and being well over 200 lbs.
They must be rather heavy to burn over 800 calories in a hour and running or something similar.... or they're putting in more calories than they're actually burning.
here's a list:

most calories burned:
--boxing
--rowing
--Cross country skiing, racing
--Cycling, >20mph, racing0 -
That sort of impies I don't give 110%, which I do. I seriously can't be in any more pain. I only need to lose about 15-20 lbs and an hour of Zumba (with HRM) also only burns 400-500 cals for me.
I think we weigh around the same?? I am 5'5" and 137 pounds. I burn around 400 for an hour of Zumba and around 600 for an hour of running. I run at about 85% of my max heart rate unless I am sprinting. I wondered the same about these huge calorie burns I see.0 -

I wear a bodybugg and i agree with you 300-400 calories is the max i burn in an hour session (which is running on the treadmill at 6.0 and weight lifting)
oh and i took a cardio kickboxing class and only burned barely over 400 and that was intense (i weigh about 145lbs)0 -
I'm 340ish and I worked out yesterday and burned the following (according to the machines):
Elliptical at levels 10-13 for 27 minutes: 381 calories burned
Arc Trainer at varying inclines between 5-10 and varying resitances between 60-100 for 30 minutes: 739 calories burned
I take into account that the machines are overestimating my calories burned, so I only log 85%. That still gives me 323 for the elliptical and 628 for the arc trainer, so that means for 57 minutes of cardio I burned an estimated 951 calories.
I am obese and I keep my heart rate between 180 and 190.0 -
it all depends on the type of activity and the level of intensity i can easly burn up to 800 cal in an hour, more if i really push myself. cardio activites like jogging over 6 mph and even using the elliptical with high resistance and a decent speed will get you burning more than walking or moderate cycling. duration isn't the key, exertion is. I am NOT saying that you have to go hard or go home just answering your question.0
-
It really does depend a lot on your size and how hard you're working. I can burn 700 calories in an hour on the elliptical if I have the resistance way up and my heart rate stays up the whole time. But I'm 5'6" and 180lbs, you might be significantly smaller and therefore burn a good bit less! And guys usually burn a lot more than women do because they have more muscle mass.A lot of people here seem to burn ^^ that many calories in one session of exercise, sometimes the title does not even seem to be vigorous exercise.

No ine is saying you dont give 110% but you have 15-20lbs to lose and alot of people on here including myself have up to a 100lbs and even more to lose so people weighing more sre going to burn more0

Thermal stress
Question for you Azdak, are you familiar with how much thermal stress may skew the results? Is it a minor discrepancy or can it be a major one?
It can be substantial.
Example: a yoga class might burn 300-400 calories. During hot yoga, people will get HRM counts double and triple that number. The extra number is due to the thermal stress (no extra calories are actually being burned).
That's probably an extreme example, but I would say that, for someone 170-200 pounds, thermal stress could make a difference of 2-5 calories a minute.
There is also something known as cardiovascular drift. During a longer workout, heart rate will steadily increase with no change in workload. When I do a 45 stairmaster workout, even a fairly easy one, my HRM calorie count for the 2nd half of the workout is easily 30% higher than the first half (sometimes 100+ calories difference in 22.5 min), even though neither my workload nor my breathing has changed.
It's one of the many reasons why I caution people about HRM calorie readings -- not to see them as precise measurements. The average HRM is set up to estimate calories only during steady-state aerobic exercise. If set up properly, it might reach about 85%-90% accuracy under those strict conditions.Every variation away from that "ideal" set of conditions diminishes the accuracy.0 -
I'm 214 lbs (down from 289 last year). I burn 800-1000+ cals in a one-hour high intensity spin class. I rarely hit 1000 anymore, but when I was heavier, I did all the time. I use a heart rate monitor that's set up properly and it corresponds well with my road bike computer, too. However, the default MFP numbers that pop up when I log my calories are always low by a lot. However, I think I work harder than almost everyone in any class I've been too. The average spin class participant is usually coasting along. But the interesting thing is that the difference between easy going and misery is only a few hundred calories in an hour. It's probably not worth it (unless you are seriously time crunched or something), but I go to not only lose weight, but to make myself faster on my real bike.0

I easily burn over 800 calories in an hour Zumba class...but of course I weigh 240 pounds and not 140 pounds. I reach my target heart rate probably quicker than you do. I also wear a heart rate monitor to see how many calories I'm burning. I found that MFP always overestimated calories burned for some reason. This way it makes my weight loss a little more accurate.0

Here is the very simple fact. Any physical activity that bumps up your HR in Zone 5 which is 90-100% from your max HR can burn up to 20 cals/min. You do the math now.
Here is some details.
Zone 5a: Threshold Endurance
Also known as: Superthreshold
% Lactate Threshold: 100%-102%
% VO2 Max: 91%-93%
% Max Heart Rate: 91%-93%
RPE Scale: 17
Used for: Intervals, hill work, and tempo work; typically used after some Zone 4 time has already been done. Zone 5 workouts are very short because it is difficult to maintain this level for any length of time.
Zone 5b: Anaerobic Endurance
Also known as: Speed Endurance
% Lactate Threshold: 103%-105%
% VO2 Max: 94%-98%
% Max Heart Rate: 94%-98%
RPE Scale: 18-19
Used for: Intervals and hill work to improve anaerobic endurance. Intervals in this zone generally have work-to-rest ratio of 1:1, for example, a 20 second sprint followed by 20 seconds of easy recovery (Zone 1).
Zone 5c: Anaerobic Capacity
Also known as: Power
% Lactate Threshold: 106%+
% VO2 Max: 98%-100%
% Max Heart Rate: 98%-100%
RPE Scale: 20
Used for: Short-term Sprinting. Intervals in this zone have a work to rest ratio of 1:2 or more.

It's all about the resistance, I can burn a lot on the elliptical, much more than I can on a bike!I agree and the MFP numbers are usually way over the top. I typically take 25-50% off what it recommends if I am not tracking with HRM myself.
Also, soooo many people keep saying they are using the elliptical machines. I find this the most useless workout for HR and therefore cal burn. Not much better than a recline bike! I don't know how you can burn 800 on the thing, I have only even burnt about 200-300 cals on one.

The more fit individual will burn fewer calories than a less fit person all things being equal. Being fitter, their body is more efficient and requires less energy to perform the exercise.
An HRM calculates off of your Heart Rate, Go figure, and a fit person has a harder time getting their heart rate up so their calories burned is less.0 -
Somedays I have massive burns from my work outs other days I don't. I wear an HRM. I also noticed that once my body is use to an exercise or routine I tend to burn less, so I switch it up a little.
Everyones metabolism is different.0 -
Weight, level of intensity, where the numbers are coming from, etc....all variable in determining one's burn.
I use my HRM to track myself and don't give a hoot what others use.0 -
I hope that AZDAK sees my posts and comments on what I have done....
I recently adjusted my HRM because of this. I am 6 ft tall and am down from 230 to 172. I have a Polar ft7 and when I run, my average Heart rate is 176-180 and a peak of up to 194 depending on the day, this is for 45 minutes to an hour of running. I often burn over 1,000 calories according to my HRM. Anyways back to the point. Under user settings, it takes your personal stats and gives an estimated "max HR" ( for me it says 192) and then from what I gather, it takes this "max hr setting" and compares it with your actual HR to determine % of max capacity you are working to compute calories burned.
My issue is if I can hit 194 and not be dead or in fibrillation, then obviously my max HR is higher than the 192 that polar estimates for me so the other day I moved the setting up to 196. And since then I have hit 194 a few times so I might bump it up to 200.
I do not recommend everybody do this, and I would hope that as my fitness improves that my max hr will drop for steady state cardio such as long runs.
But I attribute this to why my calories burned are 30-40% higher than some of my friends when doing running at the same speed.0
